7-2 (8) Video CD setting
It is desirable to increase the probability of correction rather than decrease the probability of error correction
for video CD in playback mode. Therefore, set the C2 correction to quadruple correction.
Set the C2 correction to triple correction when playing back an audio CD.

7-2 (9) Digital audio interface Bit V control
D7 and D5 of microcomputer command address 42h are used for the Bit V control of the digital audio interface.

ˎ Bit V ON

Note 1) The LSI in ATT mode means that the LSI is in digital attenuation, soft attenuation, or soft muting mode.
The Bit V is, however, always off if the LSI is under ʵ12 dB control for serial data attenuation with
D4 of 46h set to on.
If the Bit V is set to off in ATT mode for a TX Bit V change, the Bit V is on when the digital or soft
attenuation level is set to 0 (i.e., ʵʿ dB).
Note 2) The Bit V is always on in TX mute control or mute control through the DMUTE pin.
7-2 (10) Audio output MUTE
The microcomuputer command makes it possible to mute SRDATA output, DF/DAC output, or TX output
independently.
All outputs can be muted through the DMUTE pin.
